VMy inventionv relates to improvements in carbureters, and oneapplication of it is illustrated in the accompanyi wherein Figure 1 lisa section bureter; Fig. 2,a section along the line 2-2 of Fig. 1.

g drawings,

' Like parts are indicated by the same let' ter in all the figures.

The sly'rell, A having the ends A1, A1. and top A3 makes with the WallAfthe carburetf ing or mixing chamber A5.

l is a hydrocarbon or fuel nozzle controlled by the valve B1. C is asimilar Water or liquid nozzle, both of them discharging into thecarbureting or mixing chamber A5.

D is `a mixture discharge port in the end A1y of the. casing and D1, theconnection .vhich leads thence to the engine. n

E in' theend A2 of the casing is an air intake port in communicationwith the air intake passage E1.

The gate valves F, F1 which control the ports D and E are slidablymounted upon the opposed end Walls A1, A1, and are controlled by the thetop A3. The screw-threaded lever F is provided at either end with theslot-SF5 to on the slide rodsF2, F3, and is mounted upon the collarkF"'vvhich is adjustably held by the nuts Fs and which is pivotalllvmounted upon the lug F9, which is adjustably held upon the top A3 by thescrew F10 in the slot F11. The valves may be operated in any suitablemanner from any suitwhich is pivotally mounted upon the collar G1 which,in turn, is adjustably mounted upon the rod Ft and held in position bythe nuts G2.

lt will be evident that while I have shown in my drawings an yoperativedevice, still many Achanges might be made vin the size, shape andarrangement of parts without ldeparting materially from the spirit of myinvention and I Wish, therefore, that my ings be. regarded as in a sensediagrammatic.

It will be understood, of course, that my invention is applicable to theuse of any kind of hydrocarbon fuel such as oil, gasolene, alcohol andother similar fluids. y

The-use and operation of my device are as follows z-I provide acarburetingor mixing chamber with anair inlet and a mixture dischargecommunicating with the engine. The engine draws 4 its charge ,throughthe carbureting or mixing chamber and a vacuum is createdl yWithinv such'chamber whichdraxv the hydrocarbon vacuum operates to and `water toforma combustible'niixture from the needle valve or other liquid supply.The amount 'of gas or. air passing out' of the carbureter tisvaried tocontrol the speed of the engine land when this amount of air isvaried itwill be obvious that the vacuum in the carbureting or mixing cham-`loerfmust also be varied in order to produce a combustible mixture.This variation produce by giving the valves controlling the air intakeand mixture discharge ports. a relatively variable motion and this isdone by mounting the gate valves upon either end of the rocking lever,the position of the fulorum of which may a different relative movementto each ofthe tWo valves for the same angular displacement of the lever.The connecting rod which actuates the lever is adjustablv mountedthereon and by an empirical adjustment of the position of the fulcrumand the position of the connecting rod it will be evident that somepointmay be found at which the controlling motion of the connecting rodwill any position of the valves, bustion will then be found by startingat full load with the air intake and mixture discharge ports in the openposition. The fulcrum of the lever F4 will be Aso placed that 'for anymovement of the connecting rod G the movement of the valve F1 will belessv than that of the rod F. The engine will then beslowed down until'apoint is reached atwhich the mixture will be no longer satisfactoryeither because of too little or too much hydrocarbon', if because of toomuch hydrocarbon this will indicate too high a vacuum, and the fulcrumwill be moved toward the right, giving a lessermovement of the valve.F1; if however l'iecause ot too little hydrocarbon this will indicatetoo litt-le a vacuum, and the fulcrum will be moved be adjusted, thusgiving combustible mixture for.

and perfectcomtoward the left, givinga greater movement of the valve F1,the result being a greater.
